SPECIFICATION forming part of Letters Patent No. 666,886, dated January 29, 1901.

Application filed March 3, 1900. Serial No. 7,198. (No model.)

declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in heaters, and is a separate and distinct improvement over Letters Patent No. 524,399, granted to me under date of August 14, 1894.

The object of my present invention is to provide a device of simple and inexpensive construction by which water maybe quickly and readily heated at a small cost for any purpose desired, being especially applicable where temporary heating is desirable, and although of great service in restaurants, saloons, cafes, and other similar public places, as well as private houses, is particularly adapted for bath-room purposes; and it consists in certain peculiar and novel features of construction, arrangement, and combination of the several parts, as will be more fully described hereinafter,'and pointed out in the subjoined claims, in accordance with the statutes in such cases made and provided therefor.

Referring to the accompanying drawings, illustrating my invention, and in which like numerals of reference refer to corresponding parts throughout the several views, Figure 1 is a vertical sectional view of my improved heater, and Fig. 2 is a transverse section of same on line Ct a of Fig. 1. Fig. 3 is a top plan view of the water-distributing head, and Fig. 4 is a bottom plan view of same. Figs. 5 and 6 are sectional views of the water-distributing head, taken on lines 17 b and c a, respectively, of Fig. 3. Fig. 7 is a detail view showing a portion of the burner as broken away and in section. Fig. 8 is a side elevation of the lower portion and base of the heater, the upper portion being broken away, and showing the pipes which connect with the gas and water supply pipes of the building, thereby furnishing the heater with gas and water,and the duplex valve for regulating the flow of the same, also the pilot-light and the slotted opening in the heater through which it swings when igniting the gas in the burner.

In describing my invention in detail and having reference to the various parts thereof by means of the aforesaid numerals of reference as employed throughout the several views of the accompanying drawings, 1 indicates an outer casing or jacket, preferably of sheet metal, and provided with a removable top or hood 2, all of any preferred contour or design,and a base 3 of suitable form to support the heater when resting in operative position on a bracket or other suitable support, as desired. Top or hood 2 is formed at its base with a shoulder by which it is held or rests firmly but removably on the top of outer casing or jacket 1, while at its top it is formed with a vent or opening 4, adapted to connect with a discharge-pipe (not here shown) for the escape of all superfluous heated air and waste products of combustion, which are thus carried off up the line or into any store or garret room, as desired.

5 is an inner casing or cylinder of corrugated sheet metal, (see Figs. 1 and 2,) connected at its base with outer casing 1, from which it rises in a conical form to its top, the space between said casings or cylinders l and 5 forming a chamber or reservoir 6 for the reception of the water.

7 is conical-shaped cylindrical body of corrugated sheet metal, (see Figs. 1 and 2,) having a bottom portion 8, the space between casing 5 and cylindrical body 7 forming the outer heating or combustion chamber 9, while the interior of said cylindrical body is divided by means of a sheet-metal cylinder 10, prefer ably slightly conical in form, and a pipe or tube 11 into a large and small water-chamber l2 and 13, respectively. lheinteriorof pipe or tube 11 forms the inner heating or combustion chamber 14. The top of said pipe or tube comes a short distance below in a direct line and has a-direct communication with vent 4. Chamber 14 acts as a fine or passageway, and thus conveys the heated air and waste products of combustion as they arise in their upward course through and are carried off at their final outlet, as heretofore described.

Vater-pipe 15 and gas-pipe 16 are shown broken ofi in Figs. 1 and 8, but in practice are intended to be properly connected to the water and gas supply pipes of the building, and short vertical pipe 17 being provided with an ordinary passage-way the gas when turned on is let into pilot-light 18 by means of small cook 19, and the gas beinglighted said pilotlight is adapted to be turned orswung through slotted opening 20 in said outer casing or jacket of the heater by movinghandle 21 outward. The flamefrom thepilotwillthusignite the gas as it escapes through the numerous openings or perforations 22 in gas-burner 23. Gas-burner 23 is supported in position by means of one or more short legs 24, formed with a foot which is screwed to base 3, or said burner may be otherwise supported as desired, and as shown more especially in Fig. 7 said burner is intended to be constructed of any number of sections 26, each one of which forms on its interior a compartment, each of said compartments communicating one with the other, forming one large gasehamber 25, and in the instance shown in the drawings and more especially in Fig. 7, where I have shown a burner constructed with the top and bottom sections only, each section being provided with a series of perforations or small passages 22 for the escape of the gas to be ignited, each compartment being formed just at the top of each of said series of perforations with a flange 27, around which the gas is forced to pass in escaping through said per forations, and by constructing the burner, as here shown, with a number of compartments as desired, uniting in one larger chamber 25, I have found that the gas as fed to the burner through the pipe 28 will become more thoroughly mixed with the air, thus causing a more perfect combustion, (sec arrows in Fig. 7,) although any form of burner desired may be used, and an ordinary form of atmospheric mixer 29, located at end of pipe 28, receives gas-pipe 16.

A handle 30 operates a duplex valve of any ordinary and well-known form of construction, which thus regulates simultaneously the pressure of the flow of both gas and waterin pipes 16 and 15, respectively, and when handle 21 is moved outward to swing pilot-light when lighting the burner a valve of any ordinary construction, located within waterpipe 15 and not necessary to be shown here, permits the water to rise by its pressure in pipe 15, from whence it passes and rises in chamber or reservoir 13 and from thence into water ways or channels 31 in water-distributing head 32, and thence through the two series of openings or perforations 33 and 34in waterdist-ributing head, (see Figs. 1, 4, and 6,) and descends down the corrugated channels in cylinders 5 and 7 in two full thin even streams into water chambers or reservoirs 6 and 12, and thus being 'evenly spread over the surface of conical cylinders 5 and 7 is quickly heated by the hot air which arises in heating or combustion chambers 9 and 14, ascending from the flame of burner 23, the course of the water and gas being indicated by arrows in Figs. 1, 6, and 7. Water-distributing head 32 is supported by reason of the tops of cylinders 5, 7, and 10 hearing against the sides of or being seated in its waterways or annular channels 31, said water-distributing head being provided with small tubes which form vent-openings 35 for the escape of superfluous hot air and steam and to prevent water chamberor reservoir 12 from becomingairbound ,said water-distributing head being provided on its top surface with a small vertical flange 36, which forms a seat or bearing for flue 37, said cap being opened at its top where it meets vent 4, and this forms a guide for the superfluous heated air and waste products of combustion as they pass from the heater and are carried off through a discharge-pipe up the flue.

Pipe or tube 11 is held in position at its base by a screwthreaded connection with bottom 8, while it is held in position at its top, Where it passes through a central opening 38 in said water-distributil'lg head, by a screwthreaded connection with nut 39 and washer 40, which rests on top of the water-distributing head, thus holding said head in position.

When it is desired to clean the interior of the heater, all that is necessary is to turn off the supply of water and gas, and by opening small cook 41, located at the elbow which conneets the vertical and horizontal arms of water-pipe 15, the heater may be drained of all water. Then remove top or hood 2, which is formed with the annular shoulder at its base, by which it rests tightly but detachably on the top of the outer casing or jacket. Then remove fine 37, nut 39, and washer 40, when pipe 11 may be quickly disconnected from bottom 8, leaving the interior of the heater accessible.

Short pipes 42 connect inner water chant her or reservoir 12 with outer water chamber or reservoir 6 and form conduits which convey the hot water from said inner to said outer chamber, the said water having its final discharge through spout 43 into the bath-tub or other receptacle, according to the purpose for which the hot water is to be used. Any number of screw-threaded openings provided with plugs 44, as desired, may be arranged in and around casing or jacket 1, adapted to be provided each with a spout 43 for stationary washbowls or other purposes, as desired, or only one spout 43, asin the instance shown in the drawings, may be used, which may be shifted to any position around the heater desired by reason of plugs 44. By employing short pipes 42 and spout 43 there will never be but a small amount of water at any time in chambers 6 and 12, as shown in Fig. 1, and by constructing the cylinders which form the heating and combustion chambers as here shown, also by constructing the cylinders which form the water-chambers of corrugated sheet metal, conical in form, a greater amount of heating-surface is presented, over which the water has to pass and is distributed in thin even stream in its course, and water can thus be quickly, easily, and economically heated.

It is of course understood that I do not limit myself to precise and exact construction of the several parts of my improved heater as in theinstance herein shown and described, as they may be somewhat modified and varied without departing from the spirit or principles of my inventionas, for example, if desired, gasolene may be used instead of gas by simplyplacing in a convenient and elevated position a tank containing gasolene, said tank having asupply-pipe leading therefrom with a generator at its end where it meets the burner. Also a water-gage may, if desired, be connected at a convenient point to the heater for the purpose of showing the line of water carried, thus obviating any danger of an overflow.
